Baremetal UDP application with ZynqMP

I am tryiing to come up with a small baremetal application to send UDP traffic to test some hardware. I found a few sample applications online that demonstrate udp functionality, but none of them are working for me right now:

I have a sample app that doesn't seem to work at the moment, at least as determined by my view of wireshark: Every time I attempt to send a udp packet, I see an ARP request come out, and I see the response coming back to the target board, but no UDP.

The main gist of the code is below, with error checking and declarations excluded for brevity.
